airseb made a valid point, only when regulations require the use of reverse to be taken into account will EFB do the same.
It is worth noting wheat regulations your airline flies to in this regard (FAA/EASA/...) and what (OPT) performance settings are used by your EFB group, as the latter defines OPT results.

Incorrect, the QRH assumes reversers to be UNLOCKED, then the applied (reverse) thrust is what is being referred to in reference to NO reverse or more, thus idle = NO reverse in Boeing QRH tables.
